摘要： PROBLEM TO BE SOLVED: To provide a vaporizing fuel control device for an internal combustion engine to comparatively facilitate machining and suppress the increase of a difference in an air-fuel ratio between cylinders. SOLUTION: The boundary of a flow in a throttle bore is spread to the rear of a throttle valve 5, the inclination end face opening 22 of a purge tube 13 is formed in a boundary position between an intake air flow in a forward direction and an intake air flow returning in a reverse direction and protruded from a throttle bore wall surface 21. When, in this state, vaporizing fuel vapor is injected through a purge tube 13, vapor flows through an intake manifold 2 as the vapor is diffused in both an intake air flow in a forward direction and an intake air flow returning in a reverse direction. This constitution causes uniform dispersion of the vapor to the cylinders and suppresses the increase of a difference in an air-fuel ratio between the cylinders.

摘要： PURPOSE:To prevent unexpected fuel lack or the like by detecting the remaining quantity of hydrogen in a metal-hydride tank over the whole range of 0 to 100%. CONSTITUTION:With the use of a nature of metal hydride(MH) such that the lattice of crystal expands so as to increase the bulk of MH as MH stores hydrogen, the bulk of MH is detected so as to estimate the remaining quantity of hydrogen. For example, with the use of electrostatic capacitance type level sensor 4 having electrode plates whose front ends are embedded in granular metal hydride, the electrostatic capacitance which varies in accordance with a quantity of hydrogen existing between two electrodes 4a, 4b having their surfaces coated with an insulation film, is detected by a detecting circuit 5, and is then converted into a remaining hydrogen quantity by a computing circuit 6. Then the quantity is delivered to a display part 7.

摘要： PURPOSE:To ensure the scavenging of smoke sensor and to make it possible to detect the concentration of smoke in high accuracy by providing the new air intake port and the exhaust gas injecting port for a selector valve at a place where pressure is higher than a gas injecting port. CONSTITUTION:One end of a smoke-concentration detecting path 50 is connected to an air intake pipe 18 on the upstream side from the connecting part of an EGR path 24. A numeral 53 indicates a gas introducing port. A smoke sensor 52 is provided in the smoke-concentration detecting path 50. A fresh-air intake port 54-1 is connected to an air filter 56. An exhaust-gas introducing port 54-2 is connected to an exhaust pipe 23 through a path 58. The pressure of the fresh-air intake port 54-1 and the exhaust-gas introducing port 54-2 is higher than the pressure of the injecting port 53. Therefore, the atmosphere and the exhaust gas can be smoothly introduced into an air intake pipe 18.

摘要： PURPOSE:To avoid adhesion of deposit to an end part of a light guiding member thereby to prevent reduction of the transmitted light amount, by providing a light transmitting member between an end face of said light guiding member and an opening at an end part of a casing so that the position of said light transmitting member is spaced from said opening a distance 1mm-1.5 times the inner diameter of said opening. CONSTITUTION:A light transmitting member 15 is provided between an end face 21 of a light guiding member 2 and an opening 13 at an end part of a casing 1. The position of the light transmitting member 5 is so set that a distance from the opening 13 of the casing 1 to the light transmitting member 5 is 1mm-1.5 times of the inner diameter of the opening. Since the gap between the light transmitting member 5 and the casing 1 is tightly sealed, the combustion chamber is completely isolated from within the casing 1, and the burning gas does not invade into the casing 1. Therefore, the reduction of the transmitted light amount due to adhesion of the deposit can be prevented, whereby the ignition time can be correctly detected.

摘要： PROBLEM TO BE SOLVED: To provide an injector capable of restraining the occurrence of a rich spike phenomenon to stabilize the combustion state. SOLUTION: An injection port 22 for injecting liquefied-petrileum gas is formed in a plate part 20 provided integrally with a valve 18 held in a housing 11 to reciprocate. The plate part 20 is guided in the state of close contact with a cylindrical part 15 communicated with the fuel passage outside the housing 11. With vibration of the valve 18, a gap permitting liquefied-petrileum gas to pass therethrough is formed between a projection 24 of a valve receiving part 16 and the injection port 22, thereby injecting the gas. Ice generated in gasifying the gas and adhering to the injection port 22 and the inner peripheral side of the cylindrical part 15 is shaken off or scraped off to be removed by the vibration of the plate part 20 caused by the vibration of the valve 18.

摘要： PROBLEM TO BE SOLVED: To provide a fuel feeder capable of improving starting performance of aninternal combustion engine while waste of a battery is restrained at a low cost. SOLUTION: When an ignition signal IG is on, a fuel pump 11 is driven. A passage selector valve 15 is turned on during a second set time T2, and a pressure regulator 16 is by-passed by a by-pass pipe 17. By this arrangement, vaporized fuel in a pipe is discharged. After the lapse of the second set time, a starter motor for starting the internal combustion engine is driven in response to ON of the starter signal. In the case when the starter signal is not turned on in the lapse of the first set time T1 after the ignition signal IG is turned on, the fuel pump 11 is stopped. After that, when the ignition signal IG is on, and the temperature of fuel in a delivery pipe 20 is higher than the temperature of fuel in the fuel tank 10 by a set value DH or larger value, the fuel pump 11 is again driven by the third set time.

摘要： PURPOSE: To keep the high controlling efficiency irrespective of the deterioration of the catalyst by correcting the feedback control factor so that the controlled air-fuel ratio may be on the rich side according to the deterioration of the O2 storage function of a catalytic converter. CONSTITUTION: The output signals of first and second O2 sensors 3, 4, an intake tube pressure sensor 5, a speed sensor 6, etc., which are arranged in the upstream and downstream of an exhaust gas control catalytic converter 2 containing palladium are received by an ECU 8. The air-fuel ratio correction factor is feedback controlled based on the signal of the O2 sensor 3, and the rich skip amount and the lean skip amount of the air-fuel ratio correction factor are increased/decreased based on the signal of the O2 sensor 4. The deterioration of the converter 2 is judged from the fluctuation width and the fluctuation period of the signal of the O2 sensor 4, and in the case of the judgement for the deterioration, the correction factor of the comparative voltage in increasing/decreasing the rich skip amount and the lean skip amount is increased, the comparative voltage is increased, and the air-fuel ratio is corrected to the rich side.
